X9C102PZ Datasheet PDF - Renesas Electronics

●The X9C102PZ is a Digitally Controlled Potentiometer. The device consists of a resistor array, wiper switches, a control section and non-volatile memory. The wiper position is controlled by a three-wire interface. It is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D and INC inputs. The position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation. This device can be used as a 3-terminal potentiometer or as a 2-terminal variable resistor in a wide variety of applications ranging from control to signal processing to parameter adjustment.
